Application filed July 26, 1910. Serial No. 573,884. j U

To all whom it may concern:

Be it known that I, WILLIAM JACKSON, a citizen of the United States, anda resident of the cit of New York, borough of Brooklyn, in t e county ofKings and State of vNew York, have invented new and useful Im rovementsin Printin -Machines, of which the following is a fu 1, clear, and exactdescription.

The invention relates to wal] paper p-rinting machines, and its objectis to provide 'certain new and useful improvements in rintingmachinesfor printing wall paper orders, whereby the paper after itreceives the imprint by the printing rolls is accurately cut lengthwisealong the contour ofthe imprint. For the purpose mentioned, use is madeof a cuttin roll rotating in unison with the printing rol s and having aperipheral cuttlng edge corresponding to the contour of the imprintproduced on the paper by the printing rolls.

' impression c linder B in the A practical embodiment of the inventionris represented in the accompanying drewings forming a part of thisspecification, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a perspective view of part of the wall paper printingmachine provided with the device for cutting the paper lengthwise alongthe contour of the imprint; and Fig. 2 is a sectional side elevation ofthe same.

The printing machineis mounted on a suitably constructed frame A, inwhich is mounted to rotate the impression cylinder B andV the rintingrolls C for producing the imprint B on the paper E passing around the psual manner. The shaft'C of each of the prlnting rolls C is provided atone end with a pinion C2, in mesh with a gear wheel F rotating in unisonwith the lmpression cylinder B, sothnt the printing rdlls G rotate inunison with each other, and each printin roll C is suplied as with inkby a suitable inking device indicated in Fi printing rolls (Jg Theprinting machine so far descri ed is Patented J une 6, 1911.

.On the delivery side of the (printingmw 'chine are arranged rolls-H vanI, of which the roll I is acutting roll and the roll H any impressionroll, and between the said rolls passesthe paper E after it has receivedthe imprint D of' the printing rolls C. The` 60 ings J held ad'ustablyon the frame A, s0 i shaft I of the roll I is journaled. in4 bearas topermit o moving the roll I closer to or farther from the roll H, whichlutter. is `v journaled in the frame A. The shaft I of the roll I isconnected by a gearing K withv the gear wheel F, so as to'rotate theroll I in unison with the printing rolls C. On the peripheral face ofthe roll I is arranged a continuous cutting edge I2, conforming in shapeto the contour D formed on the imprint D by the printing rolls C, and asthe cutting roll I rotates in unison with the printing rolls C, it is,evident thatwhen the machine is running the cutting edge I cuts thepaper E lengthwise along thecontour D of the imprint D. The paper E,after it is cut lengthwise as described,` passes over a roll L, and thenthe portion having the.im.
